Abstract: In a soft PVC (polyvinyl chloride) film (sheet) one of whose surfaces is glossy and the other is matt, the glossy surface is formed by a thin PP (polypropylene) film laminated on to the PVC film. A film of this type can be wound up simply but without folding, without the gloss effect being lost. This simplifies production of the film and also its further processing since it is no longer necessary to wind up two films folded gloss side to gloss side.

Abstract: A solid state light modulator apparatus is disclosed for displaying images represented by video signals. The system includes an array (11) of semiconductor devices having electrodes which extend over the tops of their respective devices. The devices are used, in conjunction with related circuitry, for applying sampled video signals to the electrodes. The resulting charge pattern deforms a conductive/reflective layer (14), and the deformations are converted to a viewable image by an optical system. In embodiments set forth, the electrodes are divided into separated fingers (300A, 300B) which decreases the effective grating line spacing of the light modulator and accordingly increases resolution. Also, in embodiments set forth, the electrodes are at two different levels, and the spurious light immunity of the light modulator is improved.

Abstract: A DNA sequence element, which activates or enhances expression of genes in plants has been identified and characterized. In particular, DNA segments isolated from the upstream region of the T-DNA  780  gene are capable of activating or increasing transcription levels of plant-­expressible genes in recombinant DNA-containing plant tissue. The  780  gene transcription activator is useful in general for increasing the level of expression of a gene in a plant. In particular, such activators are useful in the construction of plant-expression complexes which contain a plant-expressible gene placed under the regulatory control of the activator. Such expression complexes can be introduced into plant tissue where the inserted gene in expressed.
